Really, why? I always assumed that a straight stride was the most desirable as it puts the least strain on the horse's joints. I know slight deviations are to be expected, but why is toeing out better than straight or toeing in? Don't want to hijack your thread, but I'm curious if anyone can shed some light on this.
I'm wondering the exact thing. Toeing out is a conformational fault for all breeds. This will save time in explanation:
"Toed-Out/Lateral Deviation of Pastern from Fetlock/ Fetlock Valgus 
* An angular limb deformity that creates a toed-out appearance from the fetlock down.
* A fairly common fault
* Creates excess strain on one side of the hoof, pastern and fetlock, predisposing the horse to DJD, ringbone, foot soreness or bruising.
* The horse will tend to wing, possibly causing an interference injury. May damage splint or cannon bone.
* This conformation diminishes the push from rear legs, as symmetry and timing of the striding is altered with the rotated foot placement, particularity at the trot. Thus, stride efficiency is affected to slow the horse’s gait.
* The horse is unable to sustain years of hard work."
